If you have a custom HRTF file for OpenAL Soft, it might be better to use .zip\bin\Win32\soft_oal.dll from that tool and rename it to <path-to-game>\OpenAL32.dll because Rapture3D Game has only six predefined HRFT methods and will not allow raw ".mhr" files. However, entering a multiplayer lobby will crash the game.

The parameters concerning the field of view as well as the point of view of each of the in-game cameras are stored in a binary file named cameras.xml. There is one such file for each car in the game. They are located with other car-related data in the subfolders of: <path-to-game>\cars\models. These files can be batch edited using Dirt3FovChange although DLC cars may prove problematic as their data is reportedly stored in a different location. Conveniently, a backup of the binary files will be made in text format before attempting to modify them. This allows a quick restore of the most recent state.

This method is reliable and stable: modifications can be made on-the-fly, while in a race.
